Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

(a) The allylic secondary alcohol is oxidized to an α,β-unsaturated ketone, which is a typical Jones reagent (r) oxidation.

(b) The ketone undergoes α-oxidation to form a 1,2-diketone, characteristic of SeO₂/MeCOOH (t).

(c) Benzene is converted into phenol, a transformation carried out by Fenton’s reagent, FeSO₄ + H₂O₂ (q).

(d) The benzylic alcohol is selectively oxidized to a ketone while the terminal –OH remains unchanged; this is done by MnO₂ (p).

Therefore, the correct matching is:

$(\mathrm{a}\to \mathrm{r}),(\mathrm{b}\to \mathrm{t}),(\mathrm{c}\to \mathrm{q}),(\mathrm{d}\to \mathrm{p})$
